BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to a disposable, automatic, andenvironmentally safe packaging box.

2. Description of Related Art

The Chinese patent CN200710073781.7 of the applicant's previousapplication discloses an automatic, controllable, and telescopiccigarette box, wherein the cigarette can be retracted in and pushed outconveniently during the process of storing and taking the cigarette outwithout deformation and fracture. The present invention is realized asfollows: an automatic, controllable, and telescopic cigarette box,comprising a case body sealed by a case body with a case cover, whereina top cover is set at the cigarette outlet of the box body and connectedwith the box body, and a cigarette-pushing mechanism and a mechanism forcontrolling extension and retraction of the cigarette are set in the boxbody. The mechanism for controlling the extension and retraction ofcigarette includes a cigarette-pushing plate, and one or more pushingslide grooves are provided against the sides of the cigarette box nearthe cigarette outlet. The cigarette-pushing plate is movably fixed onthe pushing slide groove through a push button. One or morecigarette-guiding grooves are provided on the cigarette-pushing plate,wherein friction lines are formed on the cigarette-guiding groove.However, the automatic cigarette box has the following disadvantages: 1.the cigarette-pushing mechanism includes a V-shaped bend and a U-shapedcigarette-pushing plate. One end of the V-shaped bend is movably fixedon the cigarette-pushing plate, and the other end of the V-shaped bendis movably fixed on the box cover. Therefore, it is inconvenient toinstall the V-shaped bend due to its elasticity. 2. As the cigaretteoutlet of the box body is provided with a top cover, it requires a largeforce to push the top cover open due to larger resistance, wherein thetop cover is connected with a torsion spring. Moreover, it is with acomplex structure and a high cost.

DETAILED DESCRIPTION OF THE INVENTION

A disposable, automatic, and environmentally safe packaging boxaccording to the present invention, as shown in FIGS. 1-5, whichincludes a box body 1, a cigarette outlet 10 located on the top of thebox body 1, a mechanism 2 for controlling extension and retraction ofthe cigarette located inside the box body 1 and on the same side of thecigarette outlet 10, and a cigarette-pushing mechanism 3 located insidethe box body 1 and on the opposite side of the cigarette outlet 10; thecigarette-pushing mechanism 3 which includes a bottom plate 30, aV-shaped bend 31 and a U-shaped cigarette-pushing plate 32. One end ofthe V-shaped bend 31 is movably fixed on the cigarette-pushing plate 32,and the other end of the V-shaped bend 31 is movably fixed on the bottomplate 30. A snap-fit 33 is provided on the bottom plate 30, and a groove34, through which the snap-fit 33 passed, is provided on thecigarette-pushing plate 32; the bottom plate 30 and thecigarette-pushing plate 32 form an integrated structure through theengagement of the snap-fit 33 and the groove 34; after the box is filledwith a cigarette, it is very convenient and simple to install the boxjust by placing the cigarette-pushing mechanism 3 directly onto thestructure.

Wherein, the V-shaped bend 31 comprises a semi-circle formed on bothsides and at the junction of both sides, and a groove 35 is formed onthe cigarette-pushing plate 32 to accommodate the V-shaped bend 31. Whenputting in three rows of cigarettes, we can take advantage of thedepressed part of the middle row of the three rows of cigarettes,wherein the projection on the back of the groove 35 is located in thedepressed part, keeping the V-shaped bend 31 from occupying extra space.A hook 36 is provided at the bottom of the U-shaped cigarette-pushingplate 32, and a sticker 16 is provided on the side wall of the box body1 to form a groove 17 through the engagement of the hook 36, wherein thehook is relatively thin to fix the groove 17 stably due to goodelasticity. The U-shaped cigarette-pushing plate 32 can continuouslyslide in the box body 1 through the engagement of the hook 36 and thegroove 17 to prevent the U-shaped cigarette-pushing plate 32 frompushing out of the cigarette outlet 10 after the cigarettes arefinished.

The U-shaped cigarette-pushing plate 32 is provided with a push button37 on the installation back of the V-shaped bend 31, a push hole 38 isprovided on the bottom plate 30 to accommodate the push button 37, and athrough hole 11 corresponding to the push hole 38 is provided on the boxbody 1. The snap-fit 33 can slide out through the groove 34 by pushingthe push button 37 upward, wherein the cigarette-pushing plate 32 canpush the cigarette in a parallel way into the a mechanism 2 forcontrolling extension and retraction of the cigarette under the springaction of the V-shaped bend 31. The mechanism for controlling extensionand retraction of the cigarette 2 includes a cigarette-pushing plate 20,and a push button 21 fixed on the plate 20. A pushing slide groove 12 isprovided against the side of the box body 1 near the cigarette outlet10. The cigarette-pushing plate 20 is movably set on the pushing slidegroove 12 through the pull button 21. The cigarette-pushing plate 20 isprovided with one or more cigarette-guiding grooves 22, wherein thecurvature of the cigarette-guiding groove 22 engages with that of thecigarette, and the height of two side walls of the cigarette-guidinggroove 22 is higher that the radius of the cigarette-guiding groove 22.Friction lines 23 are formed on the cigarette-guiding groove 22 byresistance convex lines vertical to the direction of thecigarette-guiding groove 22, wherein a taper angle is formed by adjacentresistance convex lines in a place adjacent to the cigarette-guidinggroove 22.

The top of the box body 1 is provided with a first fold 13 and a secondfold 14 disposed on the top of the first fold 13, wherein the secondfold 14 is shorter than the first fold 13. An elastic sheet 4 isprovided between the first fold 13 and the second fold 14 to cover thecigarette outlet for dust proof and moisture proof with a very low cost.Wherein, a stopper 15 is provided on the first fold 13 near thecigarette outlet 10 to prevent the second row of cigarettes from slidingout. A certain curvature of the elastic sheet 4 can be formed by thesecond fold 14. Due to small friction between the cigarette and theelastic sheet 4, it is convenient to take the cigarette in and out,rather than block the cigarette from sliding out by forming a rightangle. In this embodiment, the elastic sheet 4 is an elastic plasticsheet.

The disposable, automatic, and environmentally safe packaging box of thepresent invention is very convenient and simple to install due to theintegrated structure formed by the bottom plate and thecigarette-pushing plate through the engagement of the snap-fit and thegroove. The cigarette outlet is provided with an elastic plastic sheetfor dust proof and moisture proof with a very low cost. In addition, thepackaging box is provided with a simple integrated structure and noveldesign.
